A company has deployed several wireless access points (APs) throughout their office building to ensure employees have connectivity as they move from one department to another. The network administrator notices that as a laptop moves away from one AP towards another, its connection does not seamlessly transition to the stronger AP, resulting in loss of connection. Which configuration change should the network administrator make to improve the roaming experience of the mobile users?
Configure all APs with the same SSID and use non-overlapping channels.
Configure all APs with different SSIDs to distinguish between different AP zones.
Disable the broadcast of SSIDs to enhance security and prevent unauthorized roaming.
Increase the transmission power of all APs to the maximum to expand coverage.
